A picture says more than a thousand words. This is why the world is moving away from text to images and videos. We, as Makers, can profit from this movement because we get dirt cheap hardware to play with. And if it works with an ESP32, even better. Time for a closer look.
I am a proud Patreon of GreatScott, Electroboom, Electronoobs, and others.
In this video I will:
- Compare the features of the four boards
- Try to get all of them working. Here we will see that we have to overcome the usual obstacles
- Try to use the new class of I2S MEMS microphones presented in my last mailbag. Two of the modules have such a microphone included
- Try out two sorts of camera lenses

The ESP32-CAM has an SD-Card slot. And a big white "flash" LED.

These videos are so good! You can't imagine how much people you are helping and how much of a time saver this is.

[@nigel1964]

Thank you Andreas for taking the time to explain the differences. Its getting more interesting with the advent of the cameras. I know they have been around for a while but with the advent of Internet connectivity it gets better.

[@Average_Geo]

Boy! Great prices and lots of potential! Thanks for getting my thought juices going this morning! As usual, great video!

[@science4allworld587]

Thanks. Right timing... last month i had started playing with esp32-cam

[@TimNortonGuru]

Thank you so much for your videos. I would love to see more on cameras.

[@asdomega]

Thanks Andreas, good timing for the video. My wife ordered me to install some cameras in the parking area.

[@mtarquinio]

Thanks for another very time saving video. I have a TTGO “white” and one of the many ESP32-CAM clones myself, so I highly appreciate you sharing what you have learned so far.
I also got and M5Camera because it comes in a nice LEGO friendly case.

[@RoboNuggie]

What an excellent video, thank you Andreas...

Andreas,

[@springwoodcottage4248]

Interesting & amazingly low prices. I wonder if they have launched a bit too early, but perhaps need feedback to see which are the best directions. Perhaps in the by & by more polished versions will come, but interesting challenges now to find a use for them. Thanks for sharing such valuable experiences & all the super useful side by side comparisons.

[@avejst]

Interesting as always 👍

[@dot-bob]

Thanks for another great video. I have been toying with the idea to use the esp camera module to control a sprinkler turret to target garden pests like deer or racoons. First start with basic aiming. Then see object recognition so target deer an not people.

[@bfx8185]

I'm sitting in the first row long time :D Thank you for your review report of the boards. Two project what I have in mind is hidden security camera inside the house which is able to recognize peoples. (mostly me to start sequence like turn on the lights , heating my soldering iron :D and make a reports of overnight measurements) Second one is wide lens cam in car to record when somebody scratch my car on parking place. (you know it how it goes at supermarket parking place)

[@deanhedin1615]

Great overview. Very helpful. Thanks.

[@milindkhurd]

Thank you Sir. Ur awesome.

[@erygion]

One day I'll have a lab cat too! Great video Mr. Spiess. 😊

[@handleftman]

Hi , this board can be used to protect the zone, be installed in the door. It can be used as a control point for a smart home. For example, going to the camera, she will notice the movement and activate the microphone, using the camera you can recognize the talking person. ESP32-cam will allow you to take photos on an SD card, store and transmit data for rpi3+.

[@amsf2011]

Thank you Andreas for your wise and clever videos

[@Tarbard]

Very useful roundup. A Pi Zero + cheap cam + sd card is in the same price range though so I will stick with those for now.
